MITOFY

MITOFY annotates genes and transfer RNAs (tRNAs) in seed plant mitochondrial genomes to enable analysis of structural variation and genome-size diversity, including extensive segmental duplications, chloroplast-derived sequences, and short repeats.

Key Features:

• Annotation of genes and tRNAs: Annotates protein-coding genes and transfer RNAs within seed plant mitochondrial genomes.
• Handling genome-size variability: Manages the large size variability observed in seed plant mitochondrial genomes, exemplified by Cucurbitaceae ranges from ~390 kb to >2,900 kb.
• Detection of chloroplast-derived sequences and short repeats: Identifies and annotates chloroplast sequences and short repeated elements that contribute to genome expansion.
• Recognition of structural features: Accounts for extensive segmental duplications and nuclear-derived DNA sequences present in mitochondrial genomes.

Scientific Applications:

• Evolutionary dynamics of plant mitochondrial genomes: Supports analyses of mutation rates, genome size, and RNA editing frequency interactions in seed plant mitochondria.
• Comparative genomics in Cucurbitaceae: Enables comparative studies across species such as Cucurbita pepo and Citrullus lanatus to investigate decoupling of synonymous substitution rates, genome size, and RNA editing frequency.

Methodology:

Employs advanced bioinformatics algorithms to analyze mitochondrial DNA sequences, integrates sequence data with known genomic features to identify and annotate genes and tRNAs, and accounts for chloroplast-derived sequences and repeated elements that contribute to genome-size variation.
